DESCRIPTION:
The IDT72V801/72V811/72V821/72V831/72V841/72V851/72V851 are dual synchronous (clocked) FIFOs. The device is functionally equivalent to two IDT72V201/72V211/72V221/72V231/72V241/72V251 FIFOs in a single package with all associated control, data, and flag lines assigned to separate pins.

FEATURES:
• The IDT72V801 is equivalent to two IDT72V201 256 x 9 FIFOs
• The IDT72V811 is equivalent to two IDT72V211 512 x 9 FIFOs
• The IDT72V821 is equivalent to two IDT72V221 1,024 x 9 FIFOs
• The IDT72V831 is equivalent to two IDT72V231 2,048 x 9 FIFOs
• The IDT72V841 is equivalent to two IDT72V241 4,096 x 9 FIFOs
• The IDT72V851 is equivalent to two IDT72V251 8,192 x 9 FIFOs
• Offers optimal combination of large capacity, high speed,
   design flexibility and small footprint
• Ideal for prioritization, bidirectional, and width expansion
   applications
• 10 ns read/write cycle time
• 5V input tolerant
• Separate control lines and data lines for each FIFO
• Separate Empty, Full, programmable Almost-Empty and
   Almost-Full flags for each FIFO
• Enable puts output data lines in high-impedance state
• Space-saving 64-pin plastic Thin Quad Flat Pack (TQFP/
   STQFP)
